The rate of a country's per capita sales of bottled water for the period 2007–2014 could be approximated by s(t) = 0.29t2 − t +

25 gallons per year (0 ≤ t ≤ 7), where t is time in years since the start of 2007. Use a Riemann sum with n = 5 to estimate the total country's per capita sales of bottled water from the start of 2008 to the start of 2012. (Use a left Riemann sum to find your answer. Round your answer to the nearest gallon.) HINT [See Example 2.]

Answer:

A = 126.66\,\frac{sales}{person}

Step-by-step explanation:

Then, Riemann sum with n = 5 for the function described in the statement is:

A = \Delta t \cdot [f(1) + f(2)+f(3)+f(4)+f(5)]

A = 1\cdot (25 + 24.16+24.61+25.64+27.25)

A = 126.66\,\frac{sales}{person}

What is the value of the expression 8p4: 32, 1680,40,296,40,320
muminat

Answer:

1680

Step-by-step explanation:

nPr = n!/(n-r)!

Therefore;

8P4 = 8!/(8-4)!

we get;

    = 8!/4!

    = (8×7×6×5×4×3×2×1)/(4×3×2×1)

    = 40,320/ 24

    = 1680

Radical 2 = 1.4 So 1.4 * 6 = 8.4

a^2 + b^2 = c^2

8.4^2 + 8.4^2 = square root of c

70.56 + 70.56 = 141.12 ≈ 141

Then you must find the square root of 141 which is 11.874 ≈ 11.9

Side a = 8.4
Side b = 8.4
Side c = 11.9

Using sum or difference formulas, find the exact value of sin(165∘)
Nikitich [7]
\bf \textit{Sum and Difference Identities}
\\ \quad \\
sin({{ \alpha}} + {{ \beta}})=sin({{ \alpha}})cos({{ \beta}}) + cos({{ \alpha}})sin({{ \beta}})
\\ \quad \\
sin({{ \alpha}} - {{ \beta}})=sin({{ \alpha}})cos({{ \beta}})- cos({{ \alpha}})sin({{ \beta}})\\\\
-------------------------------\\\\

\bf sin(165^o)\implies sin(120^o+45^o)
\\\\\\
sin(120^o)cos(45^o)~+~cos(120^o)sin(45^o)\implies \cfrac{\sqrt{3}}{2}\cdot \cfrac{\sqrt{2}}{2}~+~\cfrac{-1}{2}\cdot \cfrac{\sqrt{2}}{2}
\\\\\\
\cfrac{\sqrt{6}}{4}~-~\cfrac{\sqrt{2}}{4}\implies \cfrac{\sqrt{6}-\sqrt{2}}{4}
